[0053] The intelligent lock is different from the traditional mechanical lock and is a composite lock with security, convenience, and advanced technology.

[0054] In the related art, the motor in the intelligent lock generally uses a backpack motor. The backpack motor drives the locking tongue to move telescopically through a worm and worm gear. When the backpack motor drives the locking tongue to extend out of the lock body and lock the door, the backpack motor fails and jams. Due to the irreversible worm and worm gear transmission, the indoor handle rotates and jams, and the locking tongue cannot be driven to move to open the door. Therefore, the present application provides an intelligent lock and an anti-theft door to solve or improve the problem that the motor jams and cannot open the door.

[0055] The following will describe the embodiments of the present application in conjunction with Figures 1 to 14 , the embodiments of the present application will be described.

[0056] According to an embodiment of the present application, on the one hand, an anti-jamming intelligent lock body is provided, including: an anti-jamming component, a handle, and a housing 1.

[0057] Specifically, as Figures 1 to 3 shown, the handle is rotatably connected to the housing 1;

[0058] The anti-jamming component includes:

[0059] A first transmission member 2 is slidably connected to the housing 1 along a first direction X. A first notch 201 is provided on the first transmission member 2, and the first transmission member 2 is adapted to be in transmission connection with the motor;

[0060] A second transmission member 3 is slidably connected to the housing 1 along the first direction X. A second notch 301 is provided on the second transmission member 3, and the second transmission member 3 is adapted to be in transmission connection with the handle and the locking tongue 14;

[0061] The openings of the first notch 201 and the second notch 301 are arranged opposite to each other;

[0062] The clutch pin 4 can roll between the first transmission member 2 and the second transmission member 3.

[0063] In this embodiment, as Figures 1 to 3 shown, in the normal working mode of the motor, the clutch pin 4 is located between the first notch 201 and the second notch 301, and a part of the clutch pin 4 is located in the first notch 201 and a part is located in the second notch 301, and can be clamped with the first notch 201 and the second notch 301 to connect the first transmission member 2 and the second transmission member 3. The motor drives the first transmission member 2 to slide along the first direction X, the first transmission member 2 drives the second transmission member 3 to move along the first direction X, and the second transmission member 3 is in transmission connection with the lock tongue 14 to drive the lock tongue 14 to lock and unlock.

[0064] When the motor is stuck after driving the lock tongue 14 to lock, the worm and worm gear cannot drive reversely. At this time, turn the handle, and the handle drives the second transmission member 3 to move. The second notch 301 squeezes the clutch pin 4 into the first notch 201, so that the second notch 301 is disengaged from the clutch pin 4, and the handle drives the second transmission member 3 to continue to move and drive the lock tongue 14 to unlock.

[0065] In some embodiments, as Figures 5 to 9 shown, the first transmission member 2 is provided with a first sliding hole 202 extending along the first direction X, the second transmission member 3 is provided with a second sliding hole 302 extending along the first direction X, and the housing 1 is provided with a first limiting post 17. The first limiting post 17 respectively penetrates through the first sliding hole 202 and the second sliding hole 302 and is slidably connected therewith to limit the sliding distance of the first transmission member 2 and the second transmission member 3 along the first direction X.

[0066] In a further embodiment, as Figures 8 to 9 shown, both the first sliding hole 202 and the second sliding hole 302 are waist-shaped holes.

[0067] In one embodiment, as Figures 7 to 9 shown, the clutch pin 4 includes a rolling section 401;

[0068] The depth of the first notch 201 along the second direction Y is not less than the diameter of the rolling section 401, the width of the first notch 201 along the first direction X is not less than the diameter of the rolling section 401, and the second notch 301 can accommodate part of the rolling section 401;

[0069] In the normal working state of the motor, the first notch 201 applies an oblique force to the second notch 301 through the rolling section 401 to drive the second transmission member 3 to move along the first direction X;

[0070] When the motor is jammed, the second transmission member 3 moves along the first direction X, driving the second notch 301 to squeeze the rolling section 401, driving the rolling section 401 to move along the second direction Y and be completely received within the first notch 201, so that the first transmission member 2 and the second transmission member 3 are disengaged;

[0071] Wherein, the second direction Y is perpendicular to the first direction X.

[0072] In this embodiment, as Figures 1 to 3 and Figures 8 to 9 shown, under normal working conditions, the first part of the rolling section 401 is located within the first notch 201, the second part of the rolling section 401 is located within the second notch 301, and the rolling section 401 can connect the first transmission member 2 and the second transmission member 3;

[0073] When the motor drives the lock tongue 14 to lock and then the motor jams, the worm and worm gear cannot drive reversely, and the first transmission member 2 cannot move downward. Therefore, when the first transmission member 2 and the second transmission member 3 are connected, the lock tongue 14 cannot be unlocked. The rolling section 401 can move within the first notch 201. At this time, turn the handle, and the handle drives the second transmission member 3 to slide downward. The rolling section 401 is squeezed by the second transmission member 3 into the first notch 201, that is, the second part of the rolling section 401 is disengaged from the second notch 301, so that the second transmission member 3 is disconnected from the first transmission member 2. The second transmission member 3 is not restricted by the first transmission member 2 and slides downward. The second transmission member 3 drives the lock tongue 14 to move to unlock.

[0074] As Figures 1 to 3 and shown in FIGS. 7 to 9, the handle drives the second transmission member 3 to move. The second notch 301 exerts a component force on the rolling section 401 along the second direction Y and away from the second transmission member 3, so that the rolling section 401 forms a tendency to move towards the first notch 201. And the depth of the first notch 201 is not less than the diameter of the rolling section 401. The rolling section 401 can be received within the first notch 201, so that the second transmission member 3 is disconnected from the first transmission member 2. The handle drives the second transmission member 3 to slide, and the second transmission member 3 drives the lock tongue 14 to move to unlock.

[0075] The receiving depth of the second notch 301 for the rolling section 401 is the radius of the rolling section 401. Therefore, when the motor is locked, the handle drives the second transmission member 3 to move, and can extrude the second part of the rolling section 401 entering the second notch 301, so that the rolling section 401 completely enters the first notch 201 and is separated from the second notch 301.

[0076] In some embodiments, as Figure 3As shown, a fixed shaft 20 is provided on the housing 1. The first transmission member 2 is a plate body. The two sides of the first transmission member 2 along the second direction Y are respectively in sliding contact with the fixed shaft 20 and the side plate of the housing 1, preventing the first transmission member 2 from moving along the second direction Y.

[0077] In some embodiments, the rolling section 401 is a cylinder.

[0078] In one embodiment, as Figures 7 to 9 shown, the clutch pin 4 further includes a limiting plate 402. The limiting plate 402 is connected to the rolling section 401. An installation gap 5 is provided between the first transmission member 2 and the side wall of the housing 1. The limiting plate 402 is arranged in the installation gap 5, and the two side surfaces of the limiting plate 402 are respectively in sliding contact with the first transmission member 2 and the side wall of the housing 1.

[0079] In some embodiments, as Figure 3 and Figures 6 to 9 shown, the limiting plate 402 is in sliding contact with the first transmission member 2 and the side wall of the housing 1, which can prevent the rolling section 401 from disengaging from the first notch 201, ensuring that the rolling section 401 can move within the first notch 201 and the second notch 301 and move along the first direction X with the first transmission member 2.

[0080] In some embodiments, as Figure 7 shown, the abutting plate is a circular plate and is coaxially connected to the rolling section 401.

[0081] In one embodiment, as Figure 1 、 Figure 2 and Figure 10 shown, it further includes a dial 7. The dial 7 is rotatably connected to the housing 1. A connecting hole 701 is formed on the dial 7. The connecting hole 701 is rotatably connected to the second transmission member 3 through a pin shaft 26. An activity gap 6 is provided between the pin shaft 26 and the connecting hole 701. The dial 7 is adapted to be connected to a handle.

[0082] In this embodiment, as Figures 1 to 2 、 Figures 7 to 9 and Figure 10As shown, turning the handle drives the paddle 7 to rotate. The paddle 7 drives the second transmission member 3 to slide downward along the first direction X. The second notch 301 abuts against the rolling section 401. The second notch 301 exerts a component force on the rolling section 401 along the second direction Y and away from the second transmission member 3. The wrapping range of the second notch 301 on the rolling section 401 is smaller than that of the first notch 201 on the rolling section 401, which can squeeze the rolling section 401 into the first notch 201. The second transmission member 3 is disconnected from the first transmission member 2. The second transmission member 3 is not restricted by the first transmission member 2 and continues to move downward along the first direction X to drive the lock tongue 14 to unlock. There is an activity gap 6 between the pin shaft 26 and the connection hole 701, which can ensure that when the paddle 7 makes a circular motion to drive the second transmission member 3 to move linearly along the first direction X, there is no jamming.

[0083] In some embodiments, such as Figure 5 and Figure 6 shown, a fixing hole 23 is formed on the second transmission member 3, and the pin shaft 26 is connected to the fixing hole 23.

[0084] In one embodiment, as Figure 10 shown, it further includes a connecting shaft 8. The connecting shaft 8 is rotatably connected to the housing 1. The first end of the connecting shaft 8 is adapted to be connected to the handle, the second end of the connecting shaft 8 is connected to the paddle 7, and at least two first protrusions 801 are provided on the outer side wall of the connecting shaft 8. Each first protrusion 801 is arranged at equal intervals along the circumferential direction of the connecting shaft 8;

[0085] The paddle 7 is provided with a mounting hole, and at least two second protrusions 702 are provided on the inner wall of the mounting hole. Each second protrusion 702 is arranged corresponding to each first protrusion 801 along the circumferential direction of the connecting shaft 8. Along the circumferential direction of the connecting shaft 8, an avoidance gap 10 is provided between adjacent second protrusions 702 and first protrusions 801.

[0086] In this embodiment, as Figure 5 , Figure 10 and Figure 11 shown, the motor drives the first transmission member 2 to slide upward along the first direction X. The first transmission member 2 is connected to the second transmission member 3 through the rolling section 401. The first transmission member 2 drives the second transmission member 3 to slide upward, and the second transmission member 3 drives the lock tongue 14 to perform a locking action. At the same time, the second transmission member 3 drives the paddle 7 to rotate. The paddle 7 rotates with the handle through the transmission shaft. In order to prevent the handle from rotating when the motor drives the lock tongue 14 to perform a locking action, an avoidance gap 10 is provided between the first protrusion 801 on the drive shaft and the second protrusion 702 in the mounting hole, which can drive the lock tongue 14 to complete the locking action when the second transmission member 3 slides a certain displacement, and at the same time avoid driving the handle to rotate.

[0087] When the user holds the handle, if the motor drives the lock tongue 14 to perform a locking action and suddenly drives the handle to rotate, it is easy to accidentally injure the user's hand.

[0088] In some embodiments, as Figure 10 shown, four first protrusions 801 are provided, and the four first protrusions 801 are arranged at equal angles along the circumferential direction of the connecting shaft 8. The second protrusion 702 is provided as four, and the four first protrusions 801 and the four second protrusions 702 are arranged alternately along the circumferential direction of the connecting shaft 8. An avoidance gap 10 is provided between adjacent first protrusions 801 and second protrusions 702.

[0089] In some embodiments, as Figure 10 shown, the length of the avoidance gap 10 along the circumferential direction of the connecting shaft 8 can be set according to actual operation.

[0090] In one embodiment, as Figure 4 and Figure 5 shown, it further includes: one end of the elastic contraction member 11 is connected to the housing 1, and the other end is connected to the first transmission member 2;

[0091] The first direction X includes a locking direction X1 and an unlocking direction X2 with opposite directions. The second transmission member 3 moves along the locking direction X1 to drive the lock tongue 14 to perform a locking action, and the second transmission member 3 moves along the unlocking direction X2 to drive the lock tongue 14 to perform an unlocking action. Under the elastic force of the elastic contraction member 11, the first transmission member 2 has a tendency to slide along the unlocking direction X2.

[0092] In this embodiment, under normal working conditions, the rolling section 401 is engaged with the first notch 201 and the second notch 301. When the motor rotates forward, it drives the first transmission member 2 to move along the locking direction X1, drives the second transmission member 3 to move along the locking direction X1, and the second transmission member 3 drives the lock tongue 14 to perform a locking action; when the motor rotates in reverse, it drives the lock tongue 14 to perform an unlocking action. At the same time, it drives the second transmission member 3 to move along the unlocking direction X2. In order to prevent the rolling section 401 from being squeezed into the first notch 201 when the second transmission member 3 moves along the unlocking direction X2, the elastic contraction member 11 drives the first transmission member 2 to slide along the unlocking direction X2 to reduce or eliminate the pressure of the second notch 301 on the rolling section 401.

[0093] In some embodiments, the locking direction X1 is upward and the unlocking direction X2 is downward.

[0094] In some embodiments, after the motor jamming fault is eliminated, the elastic contraction member 11 can drive the first transmission member 2 to reset.

[0095] In one embodiment, as Figure 1 、 Figure 3 and Figure 13As shown, it further includes: a lock tongue dial 9, which is rotatably connected to the housing 1. A plurality of transmission teeth 901 are arranged on the circumferential side of the lock tongue dial 9, and the lock tongue dial 9 is adapted to be in transmission connection with the lock tongue 14.

[0096] A rack 12 is arranged on the second transmission member 3, and the rack 12 is in transmission connection with the plurality of transmission teeth 901.

[0097] In this embodiment, the second transmission member 3 moves along the locking direction X1, driving the rack 12 to move. The rack 12 is in transmission connection with the plurality of transmission teeth 901, driving the lock tongue dial 9 to rotate counterclockwise. The lock tongue dial 9 drives the lock tongue 14 to perform a locking action. After the locking action is completed, the lock tongue 14 is in the locked position.

[0098] In some embodiments, such as Figure 5 、 Figure 11 and Figure 12 As shown, it further includes a third transmission member 18. The third transmission member 18 is slidably connected to the housing 1 along the first direction X. The first transmission member 2 and the third transmission member 18 are arranged on both sides of the motor along the second direction Y. When the motor rotates forward, it drives the first transmission member 2 to move along the locking direction X1, driving the second transmission member 3 to move along the locking direction X1. The rack 12 drives the lock tongue dial 9 to rotate counterclockwise, and the lock tongue dial 9 drives the lock tongue 14 to perform a locking action; when the motor rotates in reverse, it drives the third transmission member 18 to slide upward. One end of the third transmission member 18 abuts against the lock tongue dial 9, driving the lock tongue dial 9 to rotate clockwise. The transmission teeth 901 on the lock tongue dial 9 drive the rack 12 to move along the unlocking direction X2. The rack 12 drives the second transmission member 3 to slide along the unlocking direction X2. At the same time, the first transmission member 2 is subjected to the elastic force of the elastic contraction member 11 and slides along the unlocking direction X2, completing the unlocking action through the drive of the motor. After the unlocking action is completed, the lock tongue 14 is in the unlocked position.

[0099] In some embodiments, such as Figure 14 As shown, two third sliding holes 1801 are arranged on the third transmission member 18. The two third sliding holes 1801 are arranged along the second direction Y and both extend along the first direction X. Two second limiting posts 19 are arranged on the housing 1 and are respectively slidably connected to the two third sliding holes 1801 to limit the sliding of the third transmission member 18 along the first direction X and the sliding distance.

[0100] In some embodiments, the third sliding hole 1801 is an oval hole.

[0101] In some embodiments, such as Figure 3 As shown, a perforation is arranged on the lock tongue dial 9, and the perforation is rotatably connected to the fixed shaft 20.

[0102] In one embodiment, such as Figure 1 and Figure 4As shown, it also includes: a lock tongue mounting plate 13 and a connecting column 15, the lock tongue mounting plate 13 is connected to a plurality of lock tongues 14, the lock tongue mounting plate 13 is slidably connected to the shell 1, a connecting hole 1301 is opened on the lock tongue mounting plate 13, the connecting column 15 is connected to the lock tongue paddle 9, the connecting column 15 passes through the connecting hole 1301, and a movable space 16 is set between the connecting column 15 and the connecting hole 1301.

[0103] In some embodiments, such as Figure 1 Figure 3 and Figure 4 As shown, the lock tongue mounting plate 13 is slidably connected to the shell body 1 along the second direction Y, the lock tongue paddle 9 is rotatably connected to the shell body 1, the connecting column 15 is arranged on the lock tongue paddle 9, the connecting column 15 passes through the connecting hole 1301, and an active space 16 is arranged between the connecting column 15 and the connecting hole 1301, which can ensure that when the lock tongue paddle 9 makes a circular motion and drives the lock tongue mounting plate 13 to make a linear motion along the second direction Y, no jamming occurs.

[0104] In some embodiments, such as Figure 1 Figure 3 and Figure 4 As shown, the second direction Y includes an extension direction Y1 and a contraction direction Y2 , the locking action of the lock tongue 14 is to move along the extension direction Y1 , and the unlocking action of the lock tongue 14 is to move along the contraction direction Y2 .

[0105] In some embodiments, such as Figure 11 and Figure 12 As shown, it also includes a torsion spring 21, a fixing column 22 is provided on the housing 1, one end of the torsion spring 21 is connected to the fixing column 22, and the other end is connected to the connecting column 15. When the lock tongue 14 switches between the locked position and the unlocked position, the torsion spring 21 is always in a compressed state, and in the locked position and the unlocked position, the elastic force of the torsion spring 21 is the smallest, and the elastic force of the torsion spring 21 has a maximum value. When the torsion spring 21 is at the maximum elastic force position and moves to the locked position or the unlocked position, the elastic force of the torsion spring 21 decreases. When the torsion spring 21 is at the maximum elastic force position and moves to the locked position or the unlocked position, it can assist in completing the locking action and the unlocking action.

[0106] In some embodiments, such as Figure 11 , Figure 12 and Figure 14 As shown, a fourth sliding hole 1302 is provided on the lock tongue mounting plate 13, and the fourth sliding hole 1302 extends along the second direction Y. A slider 1303 is provided on the lock tongue mounting plate 13. The fixed shaft 20 is slidably connected to the fourth sliding hole 1302, and is used to limit the sliding distance of the lock tongue mounting plate 13 along the second direction Y. A guide groove 27 is provided on the shell 1, and the guide groove 27 extends along the second direction Y. The slider 1303 is slidably connected in the guide groove 27.

[0107] In some embodiments, the fourth sliding hole 1302 is an oval hole.

[0108] In some embodiments, when the motor normally drives the first transmission member 2 and the second transmission member 3 to drive the lock tongue 14 to perform a locking action or an unlocking action, a force of a Newtons is required. When one of the first transmission member 2 and the second transmission member 3 is locked, applying a force of b Newtons to the other can squeeze the rolling section 401 into the first notch 201 to disconnect the first transmission member 2 and the second transmission member 3, where b is greater than a.

[0109] According to an embodiment of the present application, on the other hand, an intelligent lock is also provided.

[0110] Specifically, the intelligent lock includes the anti-jamming intelligent lock body as described above.

[0111] It should be noted that the intelligent lock includes the anti-jamming intelligent lock body provided in the embodiments of the present application, so it simultaneously includes all the above advantages of the anti-jamming intelligent lock body, and thus will not be elaborated herein.

[0112] According to an embodiment of the present application, on the other hand, the present application also provides an anti-jamming method for an intelligent lock, which is applied to the intelligent lock. The method includes:

[0113] In the normal working mode of the motor, the motor rotates to drive the first transmission member 2 to move. The first transmission member 2 is connected to the second transmission member 3 through the clutch pin 4, and the second transmission member 3 drives the lock tongue 14 to unlock.

[0114] When the motor is jammed, turn the handle. The handle drives the second transmission member 3 to move and disengage from the clutch pin 4, and the second transmission member 3 drives the lock tongue 14 to unlock.

[0115] Next, taking an embodiment as an example, in combination with Figures 1 to 14 All the above solutions will be comprehensively elaborated.

[0116] A knob 24 is rotatably connected in the housing 1. A lever 25 is provided on the knob 24. The motor is installed in the housing 1, and the motor drives the knob 24 to rotate through a worm and worm gear.

[0117] The motor rotates, driving the knob 24 to rotate counterclockwise. The lever 25 pushes the first transmission member 2 to move along the locking direction X1. The first notch 201 abuts against the first part of the rolling section 401, and the second notch 301 abuts against the second part of the rolling section 401. The first notch 201 applies an inclined force along the first direction X upward to the rolling section 401, driving the second transmission member 3 to move along the locking direction X1. The rack 12 drives the lock tongue dial 9 to rotate counterclockwise, and the connecting column 15 drives the lock tongue mounting plate 13 to move along the extending direction Y1 to perform the locking action. At the same time, the second transmission member 3 drives the dial 7 to rotate through the pin shaft 26. A clearance 10 is provided between the second protrusion 702 provided in the mounting hole on the dial 7 and the first protrusion 801 on the connecting shaft 8. Therefore, the handle will not be driven to rotate. At the same time, the torsion spring 21 switches from the unlocking position to the locking position. When the torsion spring 21 moves from the position of maximum elastic force to the locking position, it assists in completing the locking action. After that, the lock tongue 14 is in the locking position.

[0118] The motor rotates in reverse, driving the knob 24 to rotate clockwise. The lever 25 pushes the third transmission member 18 to move upward. One end of the third transmission member 18 abuts against the lock tongue dial 9, driving the lock tongue dial 9 to rotate clockwise, and driving the lock tongue mounting plate 13 to move along the contraction direction Y2 to perform the unlocking action. At the same time, the transmission teeth 901 on the lock tongue dial 9 drive the rack 12 to move along the unlocking direction X2. The rack 12 drives the second transmission member 3 to slide along the unlocking direction X2. The first transmission member 2 is subjected to the elastic force of the elastic contraction member 11 and slides along the unlocking direction X2, reducing or eliminating the pressure of the second notch 301 on the rolling section 401, preventing the second notch 301 from squeezing the rolling section 401 into the first notch 201. At the same time, the torsion spring 21 switches from the locking position to the unlocking position. When the torsion spring 21 moves from the position of maximum elastic force to the unlocking position, it assists in completing the unlocking action. After that, the lock tongue 14 is in the unlocking position.

[0119] When the lock tongue 14 is in the locking position, the motor is jammed, the knob 24 cannot rotate, and the motor cannot drive the lock tongue 14 from the locking position to the unlocking position. At the same time, it causes the first transmission member 2 to be unable to move along the unlocking direction X2. At this time, rotate the handle. The handle drives the second transmission member 3 to move along the unlocking direction X2 through the connecting shaft 8 and the dial 7. The second notch 301 squeezes the rolling section 401. The second notch 301 applies an inclined force along the first direction X downward and towards the first transmission member 2 to the rolling section 401, squeezing the rolling section 401 into the first notch 201, disconnecting the second transmission member 3 from the first transmission member 2. The rack 12 drives the lock tongue dial 9 to rotate clockwise, driving the lock tongue mounting plate 13 to move along the contraction direction Y2 to perform the unlocking action. After that, the lock tongue 14 is in the unlocking position.

[0120] Although embodiments of the present application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations fall within the scope defined by the appended claims of the present application.
